I realize that this thread is nearly 10 years old at this point, but I just came across it in a search on looking for information on Oppendorf in regards to an ancestor who left there in 1890.
Is there any way to find out more about this list of emigrants from the area? The woman I'm looking for is Henriette Hoppmann b. 1875. Supposedly, she came to the US with her older brothers, but she didn't travel with them according to the passenger list. However, they may have come to the US shortly before her arrival.
